Re: insert into select ... very very slow

you're asking a very generalized question so it is difficult to give a specific answer. however, might i suggest you first use the explain plan to analyze your select statement.

there can be many factors that effect performance of the statement: no indexes, incorrect indexes, too many indexes, fragmented data files, database architecture, locks, etc, etc.
